The Pole took the place of compatriot Szczesny. Could do nothing about the Chelsea goal after being sold short by Jenkinson, and powerless to stop Mata's bullet.
Solid defensively as he read the danger and made pertinent interventions to stop Chelsea attacks.
Worked hard up and down Arsenal's right flank but guilty of an awful header back towards his own goal for Chelsea's opener.
Not always alert to Eto'o movement but solid enough display from the Arsenal captain on his return to the side.
Zipped a shot just wide of the post in the first half as he looked to support the Chelsea attack. Solid defensively and always looked to get forward.
Busy performance in central midfield but unable to influence the game in the final third.
Arsenal's captain for the night, he kept the hosts ticking along with his precise passing but was inconsistent with his delivery in the final third.
The Czech playmaker played mainly off the left side but was largely on the periphery of the game.
Played as the playmaker in the No.10 role. Picked the ball up in good positions and produced some lovely touches but was unable to pick out the final pass. Dragged a late left-footed strike wide of the post.
The Japanese forward was given a chance on the right side of the Gunners' midfield but made no real impression despite working tirelessly for his team.
The Dane worked hard following his selection to lead the line for the hosts but movement could have been sharper as he failed to get a genuine sight of goal.
The Australian stepped in for Cech and did everything asked of him with solid handling in his box.
Opened the scoring for the visitors as he pounced on a mistake to volley in off the far post. Dealt well with the attacking threat of Rosicky and Cazorla.
The Chelsea left-back handled Arsenal's attacks with very few problems and always looked to get forward to support the visitors' forays forward.
A couple of shaky moments for the Brazilian but solid on the whole at the heart of Chelsea's defence.
Coped easily enough with Bendtner's threat. Made good decisions defensively and tidy on the ball.
J. Obi Mikel
Protected the back four well with his excellent positioning, important interceptions and efficient use of the ball.
K. De Bruyne
The Belgian struggled to find space in the final third but put in a good shift for the away side before being replaced by Ramires in the 69th minute.
The Brazilian summer signing was particularly threatening on the counterattack as he drifted in between the lines and looked to pick out incisive passes.
The Spaniard smashed home Chelsea's second goal of the game in the 66th minute with his weaker right foot to seal the victory. Constantly probing as he picked up the ball in between the lines, either centrally or on the right.
The Cameroonian led the Chelsea attack with vim and vigour. Great movement in the channels to link up play but lacked the final finish as he stabbed just wide in the second-half.
